The FAG NJ203 -E-XL-TVP2 cylindrical roller bearing, measuring 17x40x12 mm, accommodates high radial forces and unilateral axial loads in support arrangements.
This single-row cylindrical roller bearing, model NJ203 -E-XL-TVP2, is designed as a support bearing. The outer ring has two solid flanges, whilst the inner ring has a single flange. This design accommodates axial displacement of the shaft in one direction. The integrated polyamide cage guides the roller elements with low friction. As this is an open rolling bearing without sealing washers, you can integrate it directly into your assembly’s lubrication system.
Design engineers primarily use this component where high radial forces are present and defined axial guidance is required at the same time. Typical applications include shaft mountings in general mechanical engineering, which must accommodate one-sided axial forces in addition to the main load. Thanks to its dimensions – a 17 mm bore, 40 mm outer diameter and 12 mm width – the bearing is suitable for compact mounting arrangements with limited radial installation space.
The polyamide cage elastically absorbs shock loads and contributes to quiet running of the rolling element set. At the same time, the cage’s low weight reduces inertial forces during rapid changes in rotational speed. The design proves practical for assembly, as the inner ring can be removed from one side. When selecting a lubricant, the permissible operating temperature range of –30 to +120 degrees and the manufacture to tolerance class P0/PN or ABEC 1 must be taken into account.
The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows the bearing to act as a support bearing, which locks the shaft in one axial direction whilst permitting axial movement in the opposite direction. The inner ring can also be easily removed for separate installation.
The bearing has an inside diameter of 17 mm, an outside diameter of 40 mm and a width of 12 mm. These dimensions correspond to the standardised main dimensions for metric cylindrical roller bearings of this size.
The abbreviation TVP2 denotes a polyamide cage. This material is characterised by favourable friction coefficients, low weight and elastic damping properties. The cage limits the unit’s permissible continuous operating temperature range to a maximum of +120 degrees.
The bearing is manufactured with standard radial clearance. This standard radial clearance is designed for common fit selections on the shaft and housing, as well as for normal operating temperatures without extreme thermal expansion.
As this is an open bearing without integrated seals, lubrication is provided by the surrounding structure. Depending on the speed and load, options include oil circulation lubrication, an oil bath or manual grease filling during assembly with external sealing.
The permissible operating temperature range is between -30 and +120 degrees. The main limiting factors here are the polyamide cage and the lubricant selected. For applications outside these limits, versions with metal cages should be selected.
